In an experiment designed to determine the speed of light, a laser is aimed at a mirror which is 50.0 km due north. A detector is positioned 131 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector. (i) If properly aligned, what angle must the normal to the surface of the mirror form with due south? (ii) Assume that the mirror is misaligned, so that the real angle among the normal to the surface and due south is too big by 0.0050°. By how many meters (due east) will the reflected ray miss the detector?
